I first received a Poncho Liner in 1968 at Camp Eagle, Vietnam. I left Vietnam (Na Trang) in 1970 with my poncho liner (its a secret!) Through the early 1970s, my college friends slept overnight and fought to use my Poncho Liner. They all loved it. It lasted into the 1980s when my young children wore it out. They loved it as well. Since I found it on line, my son and two daughts (and I) have one. I've been ordered to get two more, one for my wife and one for my son-in-law. In short, it is very comfy!!
